Chapter 2 is devoted to study of exact solutions of the nonlinear evolution equations. Using solutions of a Bernoulli equation instead of tanh in tanh-function method we find some more general solutions of the KdV-Burgers-Kuramoto equation , and by using the nonlinear telegraph equation we show that there are many different choices on its balancing number m and the power n of the nonlinear term in Bernoulli equation by which we can recover the previously known solutions and also can derive new square root type solitary wave solutions. Exact solitary wave solutions for a surface wave equation are obtained by means of the homogeneous balance method. We also present an approach for constructing the solitary wave solutions and non-solitary wave solutions of the nonlinear evolution equations by using the homogeneous balance method directly, which is also used to find the steady state solutions, solitary wave solutions and the non-solitary wave solutions of the 2+1 dimensional dispersive long wave equations. The soliton-like solutions of the BLMP equation and the 2+1 dimensional breaking soliton equation are found by use of the symbolic-computation-based Method.

The immense suffering of the bold individual, on the one hand, and on the other the extreme jeopardy of the gods, prefiguring a "twilight of the gods"--the two together pointing to a reconciliation, a merger of their universes of suffering--all this reminds one vividly of the central tenet of Aeschylean speculation in which Moira, as eternal justice, is seen enthroned above men and gods alike.

然而，在普罗密修斯的颂歌（就其基本思想来说，它是歌颂渎神行为之作），最可惊叹的一点，是埃斯库罗斯的深厚的正义感：一方面是果敢的&个人&受尽无限痛苦，另一方面是神灵的末日定必到来况且已有朕兆，这两个痛苦境界的力量促使双方和解而产生辩证的统一；——这一切有力地暗示了埃斯库罗斯世界观的中心要点，他认为&命数&乃是统治着神与人的永恒正义。
